PullClean: Door handles as sanitizers

I'd prefer to see a handle designed for safe operation by the elbows or feet so that the hands don't need to be compromised. Think of how a surgeon enters an operating room by pushing the door with their shoulder and their hands held up out of the way.
I have never in my life seen so many motion sensor things from doors to sinks, so many sanitizer dispensers, reminders to sanitize things like keyboards/mice, and reminders/opportunities to get personal protective equipment. Like, not even at other hospitals. While he was in the ICU especially, you could tell: there was a bin for soiled linens, a bin for trash.... then a bin that was basically only used for dirty paper towels right after washing your hands because it's right next to the sink right next to the door (and sometimes there were multiple sinks in a single private room...), and usually another bin for used gowns/masks/gloves next to that since one trash bin generally wasn't enough even if it was emptied 2-3 times a day.
The dispensers especially were all over the place in your face at regular intervals in every area and at all room entrances/exits and then some, so you had no excuse not to use it (hello random visitor who told me to not push elevator buttons with my fingers because "it's a hospital and ewww germs!") While I know part of the reason for this door handle design was because people forget to use sanitizer even though they know better... even super harried ED and ICU staff were using them because it was so fast and stick-your-arm-out-in-a-second-while-leaving convenient. I don't think I saw someone _not_ do that.
I think the solution to this problem is not a door handle, but to design a hospital around this idea in the first place with the assumption that we forget - a lot of this can be retrofitted with great success.
I agree wholeheartedly.
> This is a rude interruption and will likely annoy rather than encourage more sanitization. In the video (0:59), a woman sanitizes her hands then must immediately compromise them again to actually open the door.
The idea is that you open the door with one hand and dispense sanitizer into your other hand simultaneously and then sanitize the other hand after passing through.

edit: I see Pull Clean is trying to get people to clean their hands more, but I also think it is not good to ignore an existing good strategy for eliminating germs in one of the dirtiest places (door handles) in a hospital. I am wondering how well studied this is and if it results in a cleaner environment in a hospital setting compared to installing the copper surface handles everywhere.

Alternatively I found another article sighting a study that says brass is good from 2012.

But that is absolutely NOT how they work, these gels are generally designed to be used AFTER washing your hands and only work if you rub them in for up to 30 seconds. But I would be surprised if many people knew that, *II only knew that because - and this is going to sound like total hyperbole - my life literally depends upon people washing their hands.
I think it's really interesting that when doctors, nurses or any other medical professionals come through they always wash your hands but carers always seem to rely on the magic gel. People need education as well as these tools, not instead of.

That may be true of your basic drugstore Purell, which just contains ethyl alcohol. But the literature does indicate that hospital-grade hand sanitizers (a blend of alcohols, and/or a non-alcohol equivalent) are far superior and immediately effective against most organisms.
See for example, http://cmr.asm.org/content/17/4/863.short
"Alcohols are not appropriate for use when hands are visibly dirty or contaminated with proteinaceous materials." "Alcohols are rapidly germicidal when applied to the skin, but they have no appreciable persistent (i.e., residual) activity." "Despite its effectiveness against these organisms, alcohols have very poor activity against bacterial spores, protozoan oocysts, and certain nonenveloped (nonlipophilic) viruses. Similarly, certain accepted methods for evaluating waterless antiseptic agents for use as antiseptic hand rubs require that 3 mL of alcohol be rubbed into the hands for 30 seconds, followed by a repeat application for the same duration. This type of protocol also does not reflect actual usage patterns among HCWs."
The alcohol gels are good, but I think they're not a cureall was my point.

I honestly don't know a single nurse / medical staff or even IT person in a hospital or university that thinks they are, though. You might not be giving people enough credit. Anecdotal, yes, but I've never seen people think of them as a "cureall" or even as a replacement of washing hands. It is always in addition or inbetween things where you can't get to a handwashing immediately (e.g., candidates shaking hands)shrug
So yes, anecdotes for sure. But that's one hell of a lot of anecdotes. :-)
You need to be careful with the soap you chose because hands can be "too clean" - some soaps are harsh on the skin and cause conditions suitable for bugs.

My wife works as a paediatric doctor in the NHS, and has told me that the regular use of alcohol gels leaves a slimy residue after 2 or 3 uses, prompting her to properly wash her hands (as well as wearing new gloves for every patient, obviously).
Sort of like when you throw white paint around at a rave and everybody has got their hands in the air, glowing white skin and…
Gels and hand washing are one things, but how about actually wearing gloves and changing them when you are about to touch a patient?
I think they'd really have to have some studies showing the different placement really made an impact for hospitals to buy this at scale.
This looks like a solution in search of a problem.
In any case, I still think there is risk having this ambiguous button like thing, both from passersby bumping it and from normal use. And, as my comment (and the immortal Far Side comic) illustrates, many pull doors and push doors look confusingly similar, so people will push the pull handles.
Also, may I suggest making your correction in a friendlier way next time? Especially because it is possible that the person you're correcting may not be the total doofus you imagine them to be!
Also, from what I've heard, hand sanitizers aren't great for you. Placing them on doors, encouraging (or perhaps pressuring) people to use them frequently, might do more harm than good. It would be vastly more practical and effective to strategically place motion-triggered sanitizer dispensers after doors, especially in patient rooms and on the way out of certain sections of the hospital.
It's respectable that you're thinking outside the box and looking to solve a real problem, but this needs more thought.
"... bactericidal copper touch plates on doors and handles... "
For much the same reasons as other commenters have pointed out, they have excellent antimicrobial properties. I'm moving into a new build at the moment, and we're using copper for the very same reasons. Being quadriplegic, infections are an absolute nightmare to get rid of so these things are going to be invaluable.

Because emergencies can occur anywhere, [e.g. a few years ago my sister-in-law was a code blue in the CT-room -- and that's how the staff remembered her following her recovery], doors and walls and everything below a certain height must be designed for impact by a fast moving fully loaded hospital bed.
One of the reasons door handles are so big and bulky to begin with is that's where they get hit, and they get hit to prevent damaging the door. Hospitals place scrub sinks in alcoves and up high. Same with the typical hand-sanitizer stations.
The other concern with the design is that it creates places for bacteria to 'hide' from cleaning - the seams and hinges of the door handle that allow access for refills and that operate the dispensing mechanism. Of more concern is that these are places where a health-care worker will place their hands and that by incorporating these into an architectural specialty, they are not disposable and require ongoing cleaning.
Monolithic is good. Anything that requires manipulation should fit in an autoclave or be disposable.
You want some WiFi app thingie? Ok, link the automatic doors to the nearest gel dispenser and when the ratio of door opening/dispenser use gets too low, the door only opens after the dispenser has been used.
My brother-in-law sells doors to hospitals by a wonderful coincidence. Heard so much about the damn things it's depressing.
Big Brother class 1 is your smart wifi nametag displays how long its been since you used hand sanitizer for everyone to read.
Big Brother class 2 is it also goes on your permanent record for review time and of course malpractice lawsuit time via wifi.
The idea was to cover door handles with it in hospitals etc and had received positive feedback from quite a few local hospitals if I'm remembering correctly. I'm not sure what happened to that project though. I like that solution much better than this though.
Sanitizing is more important because modern science is losing anti-biotics.
Hospital acquired infections kill a reasonable number of people and make quite a few others miserable (vomiting bugs are not fun).
